Hi everyone I am trying to do cross validation (10 fold CV) by using e1071:svm method. I know that there is an option (?cross?) for cross validation but still I wanted to make a function to Generate cross-validation indices using pls: cvsegments method. ##################################################################### Code (at the end) Is working fine but sometime caret:confusionMatrix

On an (Intel Leopard) Mac I try to build a package (mxFinance) which depends on another package (mxGraphics). The dependendy is 1) a 'Depends:' in DESCRIPTION and 2) an import in NAMESPACE. - The build fails if the dependent package (mxGraphics) is not installed in the R.framework Do I need to have installed all packages which are required by packages to be built binary (source builds

Dear list, (this is a follow up from a previous query) Why does R CMD INSTALL write most of its messages to stderr? If it wrote to stdout, then we could capture its output within an R session when calling sink("stdout.txt", type="output") install.packages("MASS", type="source") sink() As it stands, the stderr messages can't be captured via

(1) ...need to speed up a monte-carlo sampling...any suggestions about how I can get R to use all 8 cores of a mac pro would be most useful and very appreciated...

Hi all, For some odd reason when running na?ve bayes, k-NN, etc., I get slightly different results (e.g., error rates, classification probabilities) from run to run even though I am using the same random seed. Nothing else (input-wise) is changing, but my results are somewhat different from run to run. The only randomness should be in the partitioning, and I have set the seed before this

Hi. I am writing some code in C that I would like to link into R. My Makevars file is: PKG_CPPFLAGS=-I/usr/local/include PKG_LIBS=-L/usr/local/lib -lgsl PKG_CFLAGS = -Wall -O0 -g -p -pg The source file is core.c,. and I am compiling using R CMD SHLIB core.c The output is gcc -arch x86_64 -O3 -g -p -std=gnu99 -I/Library/Frameworks/ R.framework/Resources/include

In case you don't get an answer from someone more knowledgeable: 1. I don't know. 2. But it is possible that other packages that are loaded after set.seed() fool with the RNG. 3. So I would call set.seed just before you invoke each random number generation to be safe. Cheers, Bert Bert Gunter "The trouble with having an open mind is that people keep coming along and sticking

A couple of my colleagues are having problems building R-3.2.4 on Mac OS X El Capitan somehow related to libiconv. I personally don't have any problems on either of my Macs. I'm hoping thie make log might trigger something in the readers of this list: gcc -dynamiclib -Wl,-headerpad_max_install_names -undefined dynamic_lookup -single_module -multiply_defined suppress -L../../../../lib

Dear R gurus, I attempt to install the latest version of R from source on my MacBook Pro, using latest versions of Xcode and gfortran for Lion and configure options: ./configure --with-libintl-prefix=/sw --enable-R-shlib (this last option necessary to further install the Rpy Python package) I got the following unreduced compilation error: gcc -std=gnu99 -dynamiclib

Dear all, I'm trying to compile FORTRAN code to be used in R, failing miserably. I got a simple code function to try to figure out what is going wrong. Here is the code (available on the web) : subroutine bar(n, x) integer n double precision x(n) integer i do 100 i = 1, n x(i) = x(i) ** 2 100 continue end 1. I compiled the

I've been trying to get R+PostgreSQL+PL/R to work together on a OSX machine without the Framework and CoreFoundation options and have noticed some suspicious switches when compiling packages. I've installed R (on OSX) with the following ./configure: ./configure \ CC="gcc -arch i386" \ CXX="g++ -arch i386" \ OBJC="gcc -arch i386" \

You have not supplied a complete example, which would be good in this case because what you are suggesting could be a serious bug in R or a package.

I am developing a package for analysis of seismic data that relies on a Fortran library. Package compilation works fine on Ubuntu and Red Hat Enterprise but fails for R 2.15.3 on Mac OSX 10.8.4.

Thank you, everybody, who replied! I appreciate your valuable advise! I will move the location of the set.seed() command to after all packages have been installed and loaded.

Hello. I wrote a package (that contains C source) that I've been compiling and running on both Linux and Windows for about a year.

Hi all, I have a problem but i am not sure that this is the right mailing list. I'm writing a R program which call a C++ program, through the function .Call.
